Installing The Outdoor Unit In Harsh Environments - Samsung RD VHXF Series Installation Manual

INSTALLING THE OUTDOOR UNIT IN HARSH ENVIRONMENTS

• In abnormally harsh environments such as cold and/or windy areas, sufficient countermeasures to
guard against excessive wind and snow should be taken to ensure the unit's correct operation.
• Snow-proof duct(field supply) should be fitted to the unit and direct exposure to the wind should be
avoided as much as possible.
• When the unit is expected to operate in cooling mode in condition under 10°C(50°F), in snowy areas,
in environments subject to strong winds or rain, install air inlet and outlet ducting as shown below.
Note
The following problems may occur if proper countermeasures are not taken.
• The fan in the outdoor unit may stop running, causing the unit to be damaged.
• There may be no air flow.
• The condenser pressure may drop because of strong wind, and the indoor unit may freeze.
When installing ducts
• Height of frame/foundation for snow damage prevention shall be twice as high as expected
snowfall, width of frame/foundation shall not exceed that of the unit.
• The frame/foundation shall be made of angle steel, etc., and designed so that snow and wind
slip through the structure. (If frame base is too wide, snow will be accumulated on it.)
• Install unit so that wind will not directly lash against openings of inlet and outlet ducts.
